Implement opaque-enum-specifiers for C++0x.
gcc/
* tree.h (ENUM_IS_OPAQUE): New.
* dwarf2out.c (gen_enumeration_type_die): Use ENUM_IS_OPAQUE.
gcc/cp/
* cp-tree.h (SET_OPAQUE_ENUM_P): New.
(OPAQUE_ENUM_P): New.
(ENUM_FIXED_UNDERLYING_TYPE_P): New.
(start_enum): Update prototype.
(finish_enum_value_list): New prototype.
* parser.c (cp_parser_elaborated_type_specifier): Issue a pedwarn if
"enum class" is used in an elaborated-type-specifier.
(cp_parser_enum_specifier): Rewrite to parse opaque-enum-specifiers.
* decl.c (copy_type_enum): New.
(finish_enum_value_list): New, with code from finish_enum.
(finish_enum): A lot of code removed. Added a gcc_assert.
(start_enum): Add parameters enumtype and is_new.
Rewrite to work with opaque-enum-specifiers.
* pt.c (maybe_process_partial_specialization): Allow for template
specialization of enumerations, with a pedwarn.
(lookup_template_class): Update call to start_enum. Call to
SET_OPAQUE_ENUM_P.
(tsubst_enum): Call to begin_scope, finish_scope and
finish_enum_value_list.
